I noted there are 4 diifferent aspects to sighting through the rear sight RCS thats pretty cool the lower hole when the ladder is vertical what range is that on for?
Like the early No.4 flip up one was good for 300yds and when flipped the other aperture was good for 600yds

some other things to look for.
a light punch mark on the right side bolt rail, nicely polished bolt, CV marked sear, and or cocking rod. polished sight scale, black pitch on the rear sight base and front sight base,
in any event its a nice rifle and worth every penny of 1600.00
